OK
First of all: add a mute button in the main menue !!!!!
so easy, jet so important. and so many forget them.
Then: if i mute everything in-game, then it should be muted. But the lost-screen still has a sound (windblow).
Third: no upgrades ?!?! Why should anybody play this for longer than 5 minutes ?
at least it ran without bugs and had a nice graphic. So it gets 2.5 stars.
